Often ladies bikes get overly focused on styling at the expense of performance. Bicycle technology has advanced hugely in recent years and in many ways it is a shame that many ladies bikes have not benefited from it.

With the Polygon Sierra deluxe, this has certainly not been the case. With the Sierra deluxe, much case has gone into providing a complete and competent package, with comfort and performance being kept front of mind whilst designing the bike.

The all alloy step through frame is matched together with height and tilt adjustable handle bars. A suspension fork has added to provide increased comfort for both the arms and shoulders whilst riding over uneven paths. The saddle is well sprung, with elastomer supports soaking up the smaller vibrations, and with the suspension seatpost absorbing the larger bumps.

It great to see a front derailleur featured on the bike, the additional gear range makes the bike just that much more useful in all types of terrain. Usability is also furthered with the addition of a light set front and rear, a rear rack for carrying parcels as well as guard protecting the rider from drive train.

Alloy is used to keep the bike as light as possible, the use of alloy extends from the frame, to the wheels, handlebars, rear rack and even the mud guards. Keeping weight to a minimum means that the bike is that much easier to ride, especially on inclines.

A sealed bottom bracket and Shimano componentry are a given for a bike of this quality- The branded wheels and Schwalbe tyres come as a welcome surprise and add to the performance of the bike.

Just make sure you keep the box so it can be re-used to send it back. Click here for more information. 

All of our bicycles come with a Free Pro Build valued at $99. This means that your bicycle will be pre built by our professional mechanics. For your convenience, safety and comfort all our bikes are fully assembled prior to delivery. The bike is then packaged back into a box for secure shipment.

 

When your bike arrives, all you have to attach is the front wheel, the handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, and the tyres have been pumped up (please note upon arrival, in some cases you may need to add more air to tyres).

Most companies simply sell you the bike as it comes from the factory, which will require significant know-how to get your bike on the road. Currently we are the only Australian company providing this service, and have the 14 day test ride to back it up.

How does my bike arrive? Bicycles Online

Whilst your new bicycle will have already gone through our Pro Build process, you will still need to complete some minor final assembly steps when you take your bicycle out of its box.

Please follow the video playlist below to correctly complete the setup of your new bike:

 

Assembly Time:

  • 10-15min - You have assembled bikes before
  • 15-25min - You are mechanically handy
  • 30-40min - Never assembled a bike and working with tools isn't your thing

 

Unboxing your bike:

Start by carefully opening the top flap to expose the contents. You will see the bike with plenty of protective packaging and next to the rear wheel, the saddle & seatpost, a small cardboard box where your pedals, tools, bell and reflectors are. If you ordered any other products with the bike, it is likely they were placed on the bottom of the box as well. Remove all the loose items before pulling the bike out of the box and gently placing it on the floor.

Keep the box and all the protective packaging found on the bike in case you choose to change frame sizes, upgrade/downgrade the bike, or return the bike for a full refund under the 14 Day Test Ride Policy.
